A quick look at the Abrahams Jerome Gambit, with the help of The Database and Stockfish 16.1, suggests that 1.e4 e5 2.Bc4 Bc5 3.Bxf7+ Kxf7 4.Qh5+ should be answered by 4...Kf8, as it is the only move that gives Black a clear advantage.
The move 4...Kf8 appears in only 49% of the games (after 4.Qh5+) in The Database. Stockfish 16.1 (32 ply) evaluates Black as being almost 2 1/2 pawns better.
Giving Black a small advantage (1/2 a pawn) is 4...Ke6, which appears in 13% of the 1.e4 e5 2.Bc4 Bc5 3.Bxf7+ Kxf7 4.Qh5+ games.
Then follows 4...g6, which is seen in the second most games - 36% of them - but leads to a position that is evaluated as even.
Both 4...Ke7 and 4...Kf6, relatively rarely played, lead to advantage for White, each more 3 pawns.
What this means is that in the Abrahams Jerome Gambit, Black has a clearly best line of play in 1.e4 e5 2.Bc4 Bc5 3.Bxf7+ Kxf7 4.Qh5+Kf8.
However, if The Database is reflective of the club play in the larger world, White can still play the Abrahams, knowing that the defender will choose the strongest 4th move less than half of the time.
(There is one game left to be completed before players can move on to the next round in the BISHOP'S OPENING CUP 2025 tournament. The good news for impatient people is that one side is a Queen ahead; the bad news is that the time control is 1 move in 10 days.)
