20. **N2c3 Ndb4**
21. **Nd6 Qf8**
22. **Nxb7 Nd4**
23. **Nxd8 Bc5** (This move is a mistake. Instead, 23…Qf5 or 23…Qf7 keeps the pressure.)
24. **Nxe6 Bd3**
25. **Bd5 Qf5** (This move was also a mistake. Instead, 25…Nxe6 would have been stronger.)
26. **Nxd4+ Qxd5**

28. **bxc3 Qxa2**
29. **cxb4**

Now let’s look at critical moments and alternatives for Bronstein:

1. After **23. Nxd8**, instead of **Bc5**, Bronstein could play **Qf5**:

“`
23… Qf5
24. cxb4 Nxa2+
25. Nxa2 Bb3
“`

This keeps the game balanced and possibly advantageous for Bronstein by targeting the weakened d3 pawn.

2. On move **25… Qf5**, instead of **Nxe6**:

“`
25… Nxe6
26. Bxe6 Bxe6
27. Nd6 Qe7
28. Rhe1 Qf7
29. Rxe6 Qxe6
30. Nxe6 Bxe6
31. Re1 Kf7
“`

This variation shows how Bronstein could have targeted Sliwa’s weaknesses and maintained a strong position.

In summary, Bronstein missed critical opportunities to pressure Sliwa with better moves such as **Qf5** and **Nxe6**. These moves would have kept Bronstein in a winning or much stronger position.
