An experienced player is most likely to castle into a stronghold that he hopes will keep his King safe. And, when attacking the enemy’s stronghold it’s not usual that the breakthrough will be achieved by the use of pieces alone. More often than not you need a battering ram of Pawns like Lambert uses in the following game.
His opponent was the little known Stojan Puc (April 9, 1921 – January 29, 2004, 82 years old) of Yugoslavia. Chessmetrics estimates his highest rating to have been 2606 in 1951 which placed him at number 50 in the world. He was awarded the IM title in 1950 and an Honorary GM title in 1984.
The winner, Hans Lambert (March 19, 1928 – April 5, 2020, 92 years old), played for Austria in the 1950 and 1952 Olympiads. In the 1950 Olympiad, playing reserve board and won the individual silver medal, scoring +6 =4 -2. He played in tournaments until the early 1980s.

O-O O-O 8. Be3 a6 9. f4 {[%mdl 32] White almost always plays 9.a4 here to
stifle black's Q-side coumterplay. It takes great optimism to play 9.f4
because there is little hope of overrunning black's K-side position because
the fianchetto makes for a very strong fortress.} Qc7 {Much more often seen
are either 9...Nc6 or 9...Nbd7} 10. g4 {This is really going all out for the
kill. White is taking a big risk in stripping his K of its defenses. The
defensive looking 10.Bf3 is safer, but it's also pretty slow} (10. Nd5 {

gain the upper hand. Black should develop his Q-side.} (10... e5 11. Nb3 Be6 {

white did not follow up correctly and the result was a quick draw.}) 11. g5
Nfd7 12. f5 {The attack begins and already white's position is the more
promising.} Ne5 {In notes to this game from an old source the annotator
commented that as a result of white's risky attack the N cannot be dislodged
from this very useful square and it is easy to see how white's attack might
end in disaster. This is very often the problem with old annotation from book
in pre-engine days...they are often, as here, totally wrong. Stockfish
disdains 12...Ne5 and evaluates this position as 2.5 Ps in white's favor.} (

enviable, but at least white has no quick way to open up lines against the K.})
13. f6 Bh8 {It would have been more helpful for black to have a N on d7 and to
have been able to retreat his B to f8 as in the last note where at least it
would not have been totally hemmed in as here. Stiil, in this position even
though white is clearly better there is no way to force his way through to
victory.} 14. Qe1 h6 {This is suicide.} (14... b5 {is at least a gesture at a

black's defense easier.} Kh7 {White is better, but there is no easy way to dig
out black's K.}) 15... h5 {After this white has no possible P moves that
can-open the K side so he must sacrifice a piece. which he could have done
immediately.} 16. Rad1 b5 {As good a move as any; black no longer has a
satisfactory defense.} 17. Bxh5 {[%mdl 512] Notice that black has not moved
any of his Q-side pieces. Black is lost here, but a subsequent analysis shows,
the position is still quite complicated. That means there is room for wrror by
either side!} b4 (17... gxh5 18. Qxh5 Re8 19. Rf4 {Headed for h4} Ng6 {
