Wednesday Workout: Play like Gareyev

Timur Gareyev played the 'swindle of the year' at this year's U.S. Championship according to Yasser Seirawan. Missed it? Here it is, in abbreviated form:

[Event "63rd ch-USA 2019"]
[Site "Saint Louis USA"]
[Date "2019.03.23"]
[White "Sevian, Samuel"]
[Black "Gareyev, Timur"]
[Result "1/2-1/2"]
[ECO "C67"]
[WhiteElo "2642"]
[BlackElo "2557"]
[Annotator "Hartmann,John"]
[SetUp "1"]
[FEN "1r6/2p1k1p1/2pb2Pp/p1p1pP1P/1rP1K3/4B3/PPRR4/8 b - - 0 30"]
[PlyCount "13"]

{Sevian has a clear advantage in this position, but Gareyev's move only
intensifies his problems.} 30... Ra4 $2 31. a3 $1 {Effectively trapping the
rook.} Rb3 32. Rd3 $2 {It looks like there is no danger here for White.
Black's last move didn't threaten anything serious, and there's no hint of
tactical danger. How deceiving appearances can be!} ({White can avoid all the
problems by moving his rook, and} 32. Rg2 {is a useful move anyway, trying to
prepare the breakthrough on the kingside.}) 32... Rxb2 $3 {The cheapo of the
year, per Yasser Seirawan! After the game Gareyev told CLO that this shot was
not pre-planned, but rather a desperate discovery after thinking that he was
completely busted.} 33. f6+ ({The main idea is} 33. Rxb2 Rxc4+ 34. Kf3 e4+ {
and Black is winning.}) (33. Bg5+ {is another option, when play might follow}
hxg5 34. Rxb2 Rxc4+ 35. Ke3 Rh4 {and White is probably better, it's still a
game.}) 33... Kxf6 34. Rxd6+ cxd6 35. Rxb2 d5+ 36. Kf3 Rxa3 {We're left with a
position where Black has four pawns for the piece. It's completely unclear and
all three results are possible. Play continued until move 117, when Gareyev
successfully defended the infamous rook and bishop vs rook ending.} 1/2-1/2

[/pgn]

That wasn't Gareyev's only great tactical shot of the tournament. For this week's workout, can you play like he did in his Round 10 game against Ray Robson?

at the king and room for the rooks on the g- and h-files, Gareyev's attack is
getting serious!} Ne6 23. Bxf6 gxf6 $2 {Tearing the band-aid off. Now mate
cannot be stopped.} (23... Bxf6 {is forced, but still loses to} 24. Bh7+ Kh8
