How to use ‘Holes’ to WIN at Chess

Sorry about the jet noises from my computer – I’m new to this.

As always, here is the PGN:
[FEN “r1bq1rk1/pp1n1pbp/4pnp1/3p4/3P1B2/2NBPN2/PP3PPP/R2Q1RK1 w – – 0 1”]
[SetUp “1”]
1. Bd6 Re8 2. Nb5 Qb6 3. Bc7 Qc6 4. Rc1 Qa6 5. Nd6 Qxa2 6. Qc2 Rf8 7. Ra1

Reach out if you have any questions at all.
